Details

The DSM-16D is a rack mountable, dual 4-input differential binary relay tree matrix with integrated baluns and a bandwidth of over 2.5 GHz. This unit is intended to extend the input capability of a WAVECREST DTS Digital Time System from 2 single-ended to 8 differential channels by combining dual differential 4:1 switch matrices and differential to single-ended baluns.

The matrix can be controlled manually from the front panel or remotely via the RS-232C port at the back of a WAVECREST DTS Digital Time System. Remote control of the DSM-16D via GPIB commands to the DTS makes integration into an automated environment fast, without any special hardware or software.

The DSM-16D includes an RS-232C cable for connecting to the WAVECREST DTS series of Digital Time Measurement products.
